ILLUMINATION.

Specification of Letters Patent.

Patented Aug. 24, 1909.

' Application filed August 3,1908. Serial No. 446,511.

7 To all whom it may concern:

. citizen of the United States, resid in Be it known that I, SIMON H. METOALF, a g. at

Spokane, in the county of Spokane and State of Washington, have invented certain newand useful Improvements in Illuminations, of which the following is a specification.

.This invention relates to illuminations for signs,

emblems and figures of various kinds, the object being to construct a casing to con.- tain the lights that is impervious to mois" ture, dust and dirt, constructed entirely of non-combustible material.

A further object is to cheapen, lighten and simplify such constructions and "to so construct the letters, emblems and figures to be illuminated and the other portions of the mechanism, that the most possible meritorious results may be obtained in the manner of difiusing, reflecting and otherwise appropriating the lights within the casing in the way of making a clear, distinct and penetrating'light, in illuminating the vicinity and in ornamental and penetrating effect, with a view also to provide an outer surface for such casing that will permit of painting,

enameling and covering such surface with letters, emblems and figures for a day display that may be'wholly distinct and different from the night or illuminated display.

A still further object is to form such a construction in such a manner that the same may be used for either interior or exterior display or both, that is that the same may be used on the inside of buildings and in apartments as well as outside along streets and highways,with a View also. that the letters,

emblems and signs may be made readily removable and others substituted therefor.

I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which,

Figure 1, is a front elevation of a sign embodying my improvements, Fig. 2 is a vertical section of the same on the dotted line a, Fig. 3 is a front elevation of a removable 1 flat letter, Fig. t'is a front elevation of a removable raised letter with the beveled edges perforated as well as the body ofthe letter, Fig. 5 is a front elevation of a raised one piece of material.

letter with the oeveled edges unperforated, and Fig. 6 is a vertical section of Fig. 3 taken on the dotted line 6-7), showing also a light secured to the rear surface thereof protected from view through the perf0rations in the letter by a shield on either side thereof.

In a detailed description 10 indicates the casing, constructed entirely of metal, within which the lights 11 are secured, the letters 12 which may be upon one or more of the surfaces of the casing 10 are constructed of sheet metal of suitable quality, the characters 13 being formed by perforation of the body of the same in the exact formof the character desired. The letter or character is secured to the outer surface of the casing 10 by means of the guides or springs 14 secured to the casing 10 and overlapping the edges of the sheet material upon which the letters or characters areformed. In Fig. 3 I have'shown the flat letter. This gives a level surface upon which to color, paint or otherwise form letters, emblems, and charactors for a day display. While in Fig. 4: I haveshown an elevated or raised letter with the beveled edges 15 perforated. This kind of a letter or character assists inthe illumination of the space surrounding the same, while in Fig. 5, I have shown a raised letter with the beveled edges 15 unperforated. Thishas the effect of throwing the raysof lightfarther and makes the letter or character more distinct. The shields'16 are constructed of sheet metal and are also perforated in order that they may assist in diffusing the light, they serving the further purpose of. concealing the mechanical construction of the globe, socketand other mechanism within the casing 10.

' The sheet metal 12, the characters 13 and the beveled edges 15 are constructed all of The perforations through the sheet metal 12 may be filled with transparent varnish, shellac Orother translucent material thereby making the same impervious to moisture, dust or dirt.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters-Patent, is,
